I atent'ed March 30, 1909.

To all whom it may concern:

Be it known that I, ELMER L. ALLEN, a citizen of the United States, residing at Dor- 100, in the county of Schoharie and State of New York, have invented a new and useful Improvement in Adjustable Tongues for Hitchin'g Traction Engines, of which the folis a specification.

This is an improvement in set ofis for the 1 0 purpose of allowin aroad machine to run to one side .of the tea or to run directly behind the traction engine which is drawing it. The invention consists in the novel features of construction hereinafterdescribed,

' chinetobedrawm' 3 represents a beam longitudinally slotted which 18 secured to the rear of the engine and which is rovided between its end ortions with vertically arran ed rollers 4, said rollers exten transverse y'across the slotted ortion of t e beam, and between said ro ers works a slidable beam 5, said beam working at an angle to the beam 3. Oneend of the beam 5 is pivotally connected to a tongue 6 which in turn is secured in the usual manner to'the road machine 2, and the rear end portion of the beam 3 is also pivotally connected to'the tongue 6 adjacent the fifth wheel of .the road machine, the said pivotal point being d ated at 7. The road machine is provid with the usual steering wheel 8 and .nectedtot the tongue 6 and runs over the lower pulley to wheel, and a cable 14 is conthe steel-in he free end portion of the sliding beam 5 and runs over the upper pulley 10 and thence to the steering wheel. g

It will be obvious that by winding the chain 14 upon the steering rod 9 by rotation of the wheel 8 in-one direction the free end portion of the sliding beam 5 will be moved toward the beam 3hnd the parts thrown'into the position shown in Fig. 1. By reversing the rotation of the wheel 8 and winding the cable 13 upon the rod 9 the beam 5 Wlll be moved through the beam 3 in the opposite direction and the parts, brought in the position shown in Fig. 2. Continued rotation of the steering wheel will bring the tongue 6 into a position substantially parallel to the beam 3.

It will also be obvious that in assembling the parts, the ton me 6 can be connected to either end of the s iuing beam 5 so that the road machine can be run either to the right or left hand side of the road as may be desired.

Havin thus fully described my invention, what I c aim as new and desire to secure by Letters Patent is 1. A device of the kind described coriiprising a longitudinally slotted beam carried by a traction engine, a tongue carriedby a road machine, said beam being pivotally connected to the tongue at the rear end of the beam, a sliding beam pivotally connected to the free end of the tongue and working i transversely through the first mentioned beam, and means operable from the road machine for moving the sliding beam wit-h respect to the first mentioned beam.

2. The combination with a traction engine beam and a road machine ton ue, the rear end of the beam being pivotal y connected to the rear end port-ion of the tongue, a slidable beam Working through the first mentioned beam and at an angle thereto, one end of said beam being pivotally connected to the ton ue, pulleys carried by the first mentioned eam, a shaft carried by the road machine, and cables secured respectively to the tongue and the sliding beam and running over said pulleys, said cables when wound upon said shaft moving1 the sliding beam in opposite directions wit respect to the first mentioned beam.

3. An adjustable ton ue of the kind de scribed comprising a vehicle tongue, a beam secured to a draft vehicle and pivotally conl the slidable beam and running, over said neoted to said tongue adjacent the rear end pulleys, and a steering. shaft .fogalternatel y of the tongue, a slidable beam pivotally uon- Winding said cables andsliding'the slidablv nected to the free end portion of the tongue, beam in opposite" directions.

rollers carried by the first mentioned beam ELMER L. ALLEN. between which the slidable beam Works, Witnesses: pulleys carried by the draft beam, cables C. H. NEVILLE,

secured respectively, adjacent to the ends of ARTHUR CONRAD.
